Case study

Prepare the migration of the email system Lotus Notes to Microsoft office 365

There are many email migration software tools available on the market. Problem with these is that they only deal with the pure migration from old mailbox system to new mailbox system.

The preparation phase or so called pre-migration is usually not included in these tools.

What you need to do during the pre-migration:

Collect data on users and mailboxes

Check and correct the data collected.

Qualify the users and mailboxes to migrate

Create “slots” and how to make them available for the migration.

Solution

Development of a custom application to collect the data from the email system. Use of audit4mail to analyse the messaging flows

Benefits

Nicolas Chauvière, Head of communication systems at groupe Atlantic, tells us about the added value audit4mail has brought to the success of the email system migration project.

Better knowledge about the mailboxes to migrate

“audit4mail gives us a precise state of the art of the messaging usage within the group. Our IT managers can cross the data and consolidate their knowledge with the information collected by the application.”

A financial optimisation

« Groupe Atlantic has experienced a strong growth in the past years. Numerous acquisitions have led us to develop the enterprise messaging. With audit4mail we have been able to identify the mailboxes no longer used. These have not been migrated to office 365 therefore savings on migration tool licences and Microsoft subscription costs have been possible.”

A better user adoption

« We had a large number of mailboxes to migrate, for that reason we couldn’t go for a “one shot” migration. The audit4mail custom application enabled us to constitute groups of mailboxes organized by department or by project, based on the e-mail relationships. The period of co-existence of the 2 e-mail systems has run smoothly. “
